SHEET-DELIVERY APPARATUS.

SPECIFICATION forming part of Letters Patent No. 345,222, dated July 6,1.886.

Application filed September 3, 1885. Serial No.`176,084. (No model.)

T0 all whom it may concern: Be it known that I, GEORGE l. FENNER,citizen of the United States, residing at New London, in the county ofNew London and State of Connecticut, have invented new and usefulImprovements in Sheet-Delivery Apparatus, of which the following is aspeciiication.

My invention relates to improvements in sheet-delivery apparatus forprinting-presses, which improvements are especially adapted tostop-cylinder presses; and it consists, essentially, in a carrier-reeladapted to directly receive the printed sheet from theimpressioncylinder and deliver the said sheet upon a receiving-tableproperly located to receive the same. The carrier-reel is operated bysuitable levers and cams, which connect the same with the main shaft ofthe press.

The specific construction of the carrier-reel and the other operatingparts is more fully pointed out in the following specification audclaims, and illustrated in the accompanying drawings, in which- Figurelis a side elevation of a printingpress provided with my improvedsheet-delivery apparatus. of the same. Fig. 3 is a plan or top view ofthe mechanism for locking the carrier-reel and carriage.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the press-frame, constructed tosupport the impression-cylinder B and type-bed C in the proper relationto each other. At one end of the press-frame are bearings for thedrivingshaft D, from which motion is transmitted by gear-wheels D' D2 tothe main shaft E of the press, and from which shaft E motion is in turntransmitted by the usual crank, E', and connecting-rod E2, Fig. 1,to thetraveling rackwheel E3, which meshes into a stationary rack, E, on thebase of the press, and also engages a suitable rack, E5, which ispendent from the type-bed C, whereby a reciprocating motion is Fig. 2 isan end elevation cylinder is at rest during stated intervals. At a pointback of this space in the wheel B the impression-cylinder carries acatch, F, which is adapted to be engaged by a catch-lever, F', whichoperates to check, hold, andstart the impression-cylinder under theimpulse of adjusting mechanism of well-known construction. In theexample shown in the drawings this catch-lever is pivoted at f to thepressframe,a'ud is vibrated by means of a cam, F2, which has a suitableway therein, and a rod, F3, connected at one end to the lever, which hason its other end a roller-stud` f', which engages with the way in thecam F2. The end of the rod F3, which carries the rollerstud f', isslotted or bifurcated, so as to clear the main shaft E, and in order tosupportthe former a block is neatly tted into the slotted portion,through which block the shaft passes, the whole being arranged to allowthe uninterrupted motion of the connecting-rod F3. Theimpression-cylinder is provided with suitable grippers, B2, for holdingthe sheet to be printed upon the cylinder, these grippers B2 beingopened by stationary trip cams or posts B3 B4, arranged on thepress-frame in their proper relative position, and closed by suitablesprings, as usual, the whole constituting the main features of astop-revolution press of Well-known construction. p

G G area pair or racks, secured to thepressframe A in a proper alignmentwith the impression-cylinder, which racksare arranged directly over thereceiving-table II, which is also properly secured to the frame, andthese racks G G are engaged by gear-Wheels I I, which gears I I andtheir shaft I support a carrier-reeLJ, which is constructed to receivethe printed sheet from the impression-cylinder B,and transfer the sameto the receivingtable H, previously mentioned. The gears I I and theirshaft,I shall hereinafter call the reelcarriage. The gear-wheels I I, asbefore stated, are mounted 4upon a shaft', I', which extends through .ahollow spindle, K, Fig. 2, which spindle can rotate about the shaft I',and carries upon one end a gear-wheel, K', which isconstructed to engageat the proper time with a corresponding gear-wheel, K5, upon theimpression-cylinder B, so that a rotary motion is imparted to thespindle K, while the inner shaft, l', and the gear-wheels I I upon IOOthe said inner shaft remain stationary in the position shown by fulllines in Fig. l until acted upon by mechanism which will be hereinafterdescribed.

To receive the paper from the impressioncylinder, two disks, K2 K2, Fig.2, are arranged upon the hollow spindle K, which disks can be adjustedtoward or from each other and secured in such a position by suitablethumbscrews or the like. The adjustment of the disks is renderednecessary to adapt the sheetdelivery apparatus for varying widths ofsheets. manently secured to the spindle K, the said disk K3, however,only acting as a base for the sheet-gripper@ which will be hereinaftermore fully described.

It will be observed that, in order to properly deliver the sheet fromthe impression-cylinder B to the receiving-table H, the said operationmust be accomplished while the cylinder is at astop, and that thecarrier-reel-J must be retur-ned to its original position in time toreceive'the next printed sheet. This motion at the proper interval isimparted to the carrierreel, as follows: To the main shaft E of thepress is secured `a heart-cam, I, which rotates with the said shaft, andengages with a rollerstud, l, having bearings on the lower arm Aof a.lever, 1*, which is fulcrumed to the frame at li. This lever extendsupward toward carrierreel J, and its upper arm is connected with a link,15, which extends to and is in connection with the shaft I', carryingthe gears I I. To continually keep the roller-stud I3 on the lower armof lever I4 in close contact with the cam 12, I employ a rod, 16, whichis connected to A third disk, K3, is arranged and perp the other arm ofthe lever 1*, and extends; through a socket, i, on the frame of thepress, 1

`and which rod 1i has a collar, "2 thereon,l which is subjected to the`action of a spring, j

Il, coiled around the rod I, and abutting, re- 5 theaction of the springbeing in the proper direction to produce the desired result. Howeve'r,other means which would suggest themselves to askilled mechanic could beemployed to eiect the same result.

'spectively, against the socket i6 andcollar fk,

Thefmeans for removing the printed sheet;

from the impression-cylinder B, retainingthe saine on the carrier-reelJ, and releasing the said sheet at the proper moment from the carrier,consists of a set of grippers, M, Fig. 2, mounted upon a gripper-shaft,M', the said shaft-having bearings in the gear-wheel K and disk K3,which are-mounted on the said shaft. These grippers M are operated by alever, M2, fulcrumed to the disk K3, which is subjected to the action ofa suitable spring in the-ordinary manner, and is adapted to be engagedby a trip-cam, M3, secured to the receiving-table H, and also by asuitable cam, M, and the ends of these grippers impinge upon the edge ofa `radial web, K4, extending from the spindle'a'nd across the reel, soas to clamp the edge of the paper between the grippers and the web Ki.To allow the use of such an arm or partition, the disks must necessarilybe slotted. As before stated, the disks K2 K2 and disk K can rotateindependently of the shaft I and the gears I I thereon. In other words,the carrier-reel J can rotate independently of the carriage; but whenthe printed sheet iS ready for delivery to the receiving-table, andduring the linear motion ofthe reel, it is necessary that thecarrier-reel should not rotate independently, but participate in therotation of the gears I -I. For this purpose some locking device must beemployed, and in the example shown in the drawings I have made use ofthe following: Upon the main shaft E of the press is secured abevel-gear. N, which meshes into a similar gear, N,v situated upon acounter-shaft, N2, aligned at right angles to the former shaft, E, andwhich shaft has suitable bearings in the press-frame. This counter-shaftN2 has thereon acam, N3, which engages a roller-stud, n3, secured to oneend of a rod, N", which rod is suitably bifurcated to straddle the shaftat this point, and the upper end of this rod N4 is connected to a lever,N5, which is fulcru'med at n to the press-frame, while its other end isprovided with an inwardly-extending projection, at, which eugages with apin, ne, upon one arm of a lever, N6, pivoted at or near its center tothe gearwheel I. The lever N3 is provided with this inwardly-extendingprojection n* in order that when the reel-carriage moves forward in itslinear motion toward the receiving-carriage H the said lever N5 will notinterfere with its motion. As the carrier-reel is thus drawn forward bythe link`15, the pin n" clears the projection n* ofthe lever N5. Thelever N is subjected to the act-ion of a spring, nl, which constantlytends to keep the same in contact with the lever Niwhen oppositethereto. The pin n extends through a slot, n, Figs. 1 and 3, in thegear-wheel I, to allow the lever to swing about its fulcrum, and engagesat the proper intervals with a catch, n, on the gearwheel K,thereby'automatically locking the two gears, and producing the desiredresult. When the roller-stud n3 on the rod N* is not engaged by the cam,the gears and the reel are locked, but when the said rod is so engagedby the cam N the lever N6 is raised, and the pin n is thrown clear ofthe catch ng, whereby the same is released from the cam, andthe-designated parts can again rotate independently of each other.

The operation ofthe press isnow as follows: In the drawings the workingparts of the press are shown in the position they will be in when thepress has finished printing the sheets and the impression-cylinder is insuch a position that the grippers Bz'thereof are ready to grasp the nextsheet and a sheet is under the grippers of the `paper-carrier reel. Whenthe main-shaft E now continues its motion in the direction of arrow l,the type-bed C moves toward the impression-cylinder -B in the directionof arrow IOO 2 marked thereon, but does not rotatetheimpression-cylinder,since the latter is not rotated by thecatch-lever F so as to bring its teeth in contact with the rack C untilthe shaft E has made one-half of a complete revolution, which fact isdue to the contour of the cam FZ, and consequently the cylinder remainsstationary until the bed has reached its extreme position on theopposite side of the impression-cylinder. During the semi-revolution ofthe main shaft and the traverse of the bed the hollow portion of theheart-cam I2 is brought toward the roller-stud I3, on the lever I,and,owing to the action of the spring I7, the upper arm ofthe lever ILispushed outward in the direction indicated by arrow 3, carrying with itthe carrierreel J, the gears I I of which engage and travel along theracks G G. Just before the carrierreel starts in its linear motion, thepin a of the lever Nis released from the cam N3 on the shaft N2, wherebythe gears and the gear and disks of the carrier-reel are locked. Thelever I, being moved outward from the impressioncylinder, carries thethe carrier-reel therewith, the disks now rotating with the gear-wheelsI I until both have reached the position indicated by dottted lines inFig. l. During this traverse the grippers IWI on the shaft Mare openedby the lever M2 coming into contact with the spur or cam M3' on thereceiving-table, so e that the end of the sheet is released, the sheetthen falling printed face upward upon the delivery-table. On theremaining semirevolution ofthe main shaft E the carrier- 'reel J isreturned to remains in its normal position in contact with theimpression-cylinder. The carrier-reel and the reel-carriage gears I Iare again unlocked, in order to allow the reel to rotate with the saidimpression-cylinder, and the type-bed moves toward its originalposition, as shown in the drawings, but in so doing it engages with thecogwheel B of the impression-cylinder, which has been previouslysufficiently turnedby the action of the lever F2, and when in theposition shown in the drawings the grippers B2 are again in position tograsp the sheet delivered thereto from the feedtable. Since thecarrierreel J participates in the rotation of the impression-cylinder,the forward edge of the sheet printed during the preceding operation isgrasped by the grippers M of the carrierreel J, which draw the same uponthe carrierreel,whence it is delivered,as before described. Since onlytwo disks, K K2, are used in the construction of the sheet-carrier, onlythe edges of the paper come in contact with thel said reel, andconsequently the printed face is delivered unsoiled from the said reelto the receiving-table. As before stated, the sheet is held to thecarrier-reel only along one of its edges, the lower edge of thevsheetbeing free; but the entire sheet holds itself closely around the disksof the said carrier-reel during the operation of delivering the sheet tothe receiving-table, and the free end of the sheet does not `releaseitself from the carrierreel until it arrives at the proper position tofall upon the table.
